To all whom it may concern:

Be it known that 1, DAVID S. KENNEDY, of borough of Brooklyn, county of Kings, and State of New York, have invented a new 5 and useful Improvement in Line Casting which they are returned through a distributing mechanism to the magazine from which they started.

My improvementhas reference to means i for insuring the proper presentation and 2o a1inement of the matrices in front of the mold to determine the'location of the characters on the edge of the sing, and also in this connection, to means for preventing the starting of the machine unless the matrices in the proper position.

In this machine, the composed line of matrices and wedge spacers or justifiers, commonly known as the line, is trans ferred horizontally to a vertically movable support, commonly known as the first elevator. This elevator lowers the line to a position in front otthe horizontal slotted mold, which advances faceivise against the edges of the matrices, after which the elevator is 35.nrged upward in order to insure vertical alinement of the matrices by causing the cars at their lower ends to rise beneath horizontal sl'ioulder or keeper on the inold. In the commercial use of these machines,

4 0it is a common practice to substitute for one setof matrices another set having characters of a difierent size, and also a common practice to adjust the mold so as to vary the thickness of the slug therein. The location of the characters crosswise of the slug is determined by the relation which the matrices bear to the mold. It is therefore necessary to control with precision the descent of the linesupporting, elevator, and in some 0 cases to vertically adjust the alinin'g matrice shoulder on the mold, or replace it by a shoulder in a different position. All machines of this class are provided with an. automatic device actuated by the descendiior arresting the doses 1 first elevator, and, the Cllli(il1-COI1iflP improved devices h m so that if the elevator fails to lowethe matrix line to the predetermined. level, the driving clutch will be prevented iromstarting the casting mechanism.

lvly invention includes adjustable means l of the elevator and the matrix line in definite or predetermined positions, and also means connected there with for determining the action i the clu tell-cont l'Ollll'l, devices which a in thcmselws oi the for shoivnin I ti.

The accompany nn drawings are .wlslricted to those parts 6 an ordinztiry commercial lllergenth al er in ach inc \vh ich are i m me'diately associated with my invention, and it is to he understood that as to all other parts, the machine maybe oi the ordinary or any other sui tahle con struet i on.

applied ere/to.

provided with a different keeper or shout tier-plate to aline the i'natrices in a different relation to the mold.

Referring to the a awii ,s, it represents the stationary portion of the mainframe connnonl" shown as the vise-frame.

E are the matrices arranged in line side by side and presenting the characters or matrices proper in one edge opposite the mold-slot Z).

F is the vertically movable first elevator in which the line of matrices is suspended. The elevator receives the line at a level higher than that shown in the drawing, atter which it descends and lowers the line to the ing elevator to control the driving clutch conflict with the shoulders e at the lower ends bf the matrices. After the matrices have'reached the casting level, the mold advances toward them.

To the face of the mold, there is rigidly secured a so-called keeper-plate G, having on face one or more horizontal slidulders g g, to engage over the lower ears of the matrices and effect their accurate alinement when the elevator F is urged upward, as it is after the advance of the mold. I

In the present instance, I have shown. each matrix as provided withtwo independently usable characters, one above the other. Each matrix will he set into the line at a higher or lower level according as one character or the other is to be presented to the mold, and the matrix ears 6 will engage under one or the other of the shoulders 9 9, according to the height of the matrix in the line. 'lhis is well understood in the art and requires noiurthr explanation.

too far as described, the parts may all be of the ordinary construction and have the ordinary mode of action.

My first improvement relates to the means for controlling the descent of the elevator F and the contained matrix line. For this purpose, I mount in the top of the elevator F a vertical tubular screw H having its lower end in position to contact with the top of the frame A. and thereby limit the descent of the elevator. In order to permit the speedy and accurate adjustment of this stop screw H, I provide it with a flange h'notched in the periphery to admit a horizontal locking bolt h mounted in the elevator and urged forward by a spring 72. The notches in the flange it will be so disposed as to permit the setting of the screw and the stoppoge ,of the elevator in the exact positions required. Ordinarily the screw is made of such pitch and the notches so located that the turning of the screw from one notch to another will vary the height of the matrices one pointa point being the printers unit of measure. It will be observed that by means of this screw the vertical position of the matrices may be accurately controlled in relation to the Mining shoulders and the slot of the mold, so that the matrices will form a the characters in the required positions on the edge of the slug. It is to be noted that by means of the screw and devices for lockmg the same in definite positions, the attendant is enabled to accurately predetermine the position of the matrices in relation to the mold, and thereby the position of characters, of any given size, on a slug of.

any given thickness. No mechanism herei 5- fore known in the art answers this purpose. When a changens required in the location of given characters crosswise of the slug, or, when the thickness of the slug produced or the character of the matrices employed requn'athe keepenplatetir secured to the mold eoaeei by screws or otherwise, may be removed and Reference has already been made to the fact that the clutch mechanism for driving the casting mechanism is controlled by the descent of the elevator F, and to this end the vertically sliding bar a is extended at its upper end through the top of the mainframe in position to be depressed by a screw I threaded into the tubular screw H so that it may be adjusted vertically in relation thereto. The adjustment should be such that when the stop-screw H encounters the top of the frame, the screw I will hold the bar a down to the proper level to permit the action of the casting mechanism. This bar a is urged constantly. upward by a spring at. These parts correspond to the parts indicated by the same letters in U. S. Patent No. 436,532, and the bar a operates to control. the driving clutch through devices the same, or substantially the same, as those described in the patent, so that further description of these parts is unnecessary.

The essence of the present invention lies in controlling the bar at by a part carried in or forming a portion of a vertically adjustable member which controls the descent of the elevator F.

' Of course it will be understood that the screw I, seated within the screw H, is in effect a part thereof, and that the vertical adjustment of the screw H to control the operative height of the matrixline efiects the corresponding adjustment of the part casting relation to the mold, means for controlling the clutch which drives the casting mechanism, and a device carried by and vertically adjustable in the elevator, said device acting directly on the clutch-controlling means and also acting to limit the descent of the el evator. r

matrixsupporting elevator F, a clutch-controlling member a, and adjustable means for determining the height of the elevator, said means adapted also to directly actuate the bar a w 3. In. a machine of the class described, the combination of the main-frame, the matrixsupporting elevator F, a stop-screw for the elevator, means for controlling the screw to set the elevator at predetermined heights, and means for locking the screw in predetermined positions.

In combination with the frame A, the elevator F, and the clutch-controlling rod 1 a, the tubular screw 'H to control the height of the elevator, and means carried by the screw and adjustable in relation thereto to actuate the bar 6. In combination with the frame A, elein the presence of two attesting Witnesses. DAVID S. KENNEDY.
